KW BMW M3/M4 G80/G82 Height Adjustable Spring Kit

Starting with high-strength springs made from multi-coated chrome-silicon steel, this KW Height Adjustable Spring (H.A.S.) kit is built to work seamlessly with your factory adaptive or electronic suspension. Unlike traditional lowering springs that offer a fixed drop, the H.A.S. system lets you fine-tune the ride height of your 2021-2025 BMW M3, M4, or 2023+ M2 with millimeter precision, even after installation. This means you can achieve a more dynamic look and potentially improved steering response without sacrificing the comfort and functionality of your car's original electronic damping system.

KW's engineers have developed vehicle-specific spring rates that are carefully tuned to complement the characteristics of your OE dampers and wheel loads. This ensures a sporty yet harmonious driving experience, maintaining the performance dynamics expected from these vehicles. The kit includes application-specific bump stops and dust protection systems to safeguard your factory suspension components from road debris and wear. This approach offers a continuous, adjustable ride height within a tested range, a significant advantage over conventional lowering springs, and has undergone rigorous testing on the Nurburgring Nordschleife and KW's own 7-post driving dynamics test center.

This kit is designed to maintain the complete functionality of your factory electronic suspension systems, ensuring all driver assistance systems and comfort features work harmoniously. It's a well-built alternative to full coilovers when you want to lower your vehicle and have the flexibility to adjust the stance precisely.
